Based on the values and symptoms you have entered, a crude estimation of the probability of this problem can be made
If this defect is detected, it may lead to the following problems:
Ad-Blue is a mixture of 32.5% synthetic urea and 67.5% demineralized water. It is used in modern diesel vehicles to reduce nitrogen emissions. Stored in a separate tank, Ad-Blue is injected into the exhaust system, where it produces ammonia through heat.
This reacts with the nitrogen oxides in the exhaust gas and is converted into harmless nitrogen and water vapor in the SCR catalytic converter, enabling emissions to be reduced by up to 90%. As a rule, a warning message appears in the on-board computer when a remaining mileage of 2400 KM is reached. If the tank is empty, after several warnings have been displayed, the vehicle can no longer start.
